[0036] The insulating base 110 incudes a convex structure 111 on the upper surface and lower surface of the insulating base 110 respectively, to connect to the fixing unit 130.

[0037] In an embodiment, the pins 120 are outstanding in a first direction from the insulating base 110. The first direction is a direction corresponding to the length direction of the strip lamp 200.

[0038] As shown in Fig. 1, we take two pins 120 as an example to describe the embodiments of this disclosure.

When the connector 100 is used to connect the strip lamp 200 with another strip lamp, two fixing units 130 may be needed.

[0042] The material of the fixing unit 130 has a coefficient of thermal expansion less than a predetermined threshold. The predetermined threshold may be set according to actual requirements.

[0043] For example, the predetermined threshold may be set in the range of 10×10 -6< / °C - 30×10 -6< / °C, such as 17.3×10 -6< / °C.

[0044] For example, the material of the fixing unit is metal, such as stainless steel.

[0045] The fixing unit 130 is used to fix the insulating base 110 and the strip lamp 200 together. The fixing unit 130 includes two fixing parts 131, 132 for clamping the strip lamp 200.

[0056] As shown in Fig. 3, Fig. 4 and Fig. 5, a strip lamp assembly 10 includes: at least one strip lamp 200; and at least one connector 100; and a sealing part 400 for sealing a gap between the strip lamp 200 and the insulating base 110 of the connector 100, wherein the strip lamp includes: a FPCB (Flexible Printed Circuit Board) 210; multiple luminous units 220 on a first surface of the FPCB 210; at least two solder pads 230 on a second surface of the FPCB 210; and a sleeve 240 on the outside of the FPCB 210, luminous units 220 and solder pads 230.

[0071] As can be seen from the above embodiments, at least two pins for connecting to solder pads of a strip lamp and at least one fixing unit with a coefficient of thermal expansion less than a predetermined threshold are used in the connector. Therefore, it is convenient for users to assemble different lengths of strip lamps according to actual requirements, and a good electrical reliability is achieved.
